Estradiol may be obtained from natural sources or prepared synthetically. Ethinyl estradiol is one of the most potent synthetic estrogens. Exogenous estrogens elicit, to varying degrees, all the pharmacologic responses usually produced by endogenous estrogens.Advice...
Estradiol is a synthetic estrogen that may be used to treat symptoms associated with menopause or other conditions that cause low estrogen levels. Estradiol is the main type of estrogen that circulates naturally in humans. In women with menstrual periods, 70 to 500mcg of natural estradiol is ...

Although both synthetic and natural forms are available, along with different routes of administration, in the UK oral ethinyl estradiol and the low-dose oral contraceptive pill are commonly used as hormone replacement therapy for practical reasons. We present five peripubertal girls (aged 12.5–14.9...

There is no evidence that the use of natural estrogens results in a different endometrial risk profile than synthetic estrogens of equivalent estrogen dose. Adding a progestin to...
β-estradiol 17-valerate (EV) is a synthetic estrogen widely used in combination with other steroid hormones in hormone replacement therapy drugs and is detected in natural waters. EV is a reproductive toxicant and estrogenic chemical in both male and female fish [1]. 上海金畔生物科技有限公司 ...

Estradiol and its semisynthetic esters and other natural oestro- gens are primarily used as menopausal HRT (see p.2076) whereas synthetic derivatives such as ethi- nylestradiol and mestranol have a major role as compo- nents of combined oral contraceptives (see Hormonal Contraceptives, p.2069)....
